Subject: [PATCH] pstore: Fix passing zero to 'PTR_ERR' warning
Date: Sat, 31 Oct 2020 13:59:31 +0800 [thread overview]
Message-ID: <20201031055931.42844-1-yuehaibing@huawei.com> (raw)
Fix smatch warning:
fs/pstore/platform.c:320 allocate_buf_for_compression() warn: passing zero to 'PTR_ERR'
crypto_alloc_comp() never return NULL, use IS_ERR
instead of IS_ERR_OR_NULL to fix this.
